To make the best use of this guide, take the time to read it thoroughly and become familiar with its contents and organization. For quick access to information needed to answer most questions, refer to the table of contents and locate the specific item in question. To answer questions requiring more information than this guide contains, consult the documents listed previously in this introduction section. If you need additional help, contact the Premises Services Consultant (PSC). For further technical assistance, the recommended channel for AT&T System Technicians is as follows: 1. Contact your Field Assistance and Support Team (FAST). 2. If a satisfactory answer is not obtained from the FAST center, contact your supervisor. 3. Your supervisor should contact the regional staff, if necessary. Equipment Most of the items specified in this guide are available through the local AT&T Marketing Branch Office (MBO). However, some common use hardware items may have to be obtained from other sources. System Wiring System wiring plays a significant role in customers’ information systems. Technological innovations enable both voice and data transmission to be provided through the system wiring. Also, the system wiring has been simplified by reducing the number of cable pairs required by voice terminals equipped with enhanced feature options. This guide provides planning, ordering, and installation guidelines for a system Uniform Wiring Plan (Figures 1-2 and 1-3) using 110-type or 66-type hardware. 1-5 CHAPTER 1. INTRODUCTION The system switch ports for data and voice terminals require three pairs of wire per circuit. Voice terminal adjuncts require an additional pair for remote powering. To provide maximum flexibility for voice terminal changes, rearrangements, and powering, all data and voice terminal information outlets are wired with 4-pair cable. With proper administration, this will allow any voice terminal to be located at any information outlet. 1-6 System Wiring Figure 1-2. System Uniform Wiring Plan 1-7 CHAPTER 1. INTRODUCTION Figure 1-3. Sample Uniform Wiring Installation 1-8 Cross-Connect Hardware Selection Cross-Connect Hardware Selection For new wiring installations, the following cross-connect hardware is available for use in the system. Each item lists certain considerations that should help to select the appropriate hardware. 1. 110P Hardware ● Patch cord design allows customer to administer cross-connections ● Requires some technical skill to administer cross-connections 2. 110A Hardware ● Design does not permit customer participation in cross-connect administration—requires technically skilled personnel to administer cross-connections ● Hardware is less expensive than the patch cord systems, but installation and administrative costs are greater 3. 66-type Hardware ● Design does not permit customer participation in cross-connect administration—requires technically skilled personnel to administer cross-connections ● Hardware is less expensive than the patch cord systems, but installation and administrative costs are greater Obviously, the customer’s interest and preference for administering cross-connections (because of likely lower total annual costs, as well as the capability to administer the cross-connections at the most convenient time) should be given primary consideration in recommending cross-connect hardware. Figure 1-4 shows a block diagram of the equipment required to install a System 75 or 75 XE switch. The sites shown in Figure 1-4 are physical locations (closets) for pass-through connections where adjunct power may be applied. The satellite is a physical location (closet) where cross-connect administration can take place and adjunct power may be applied. 1-9 CHAPTER 1. INTRODUCTION Figure 1-4. Block Diagram of System 75 or 75 XE Installation Wiring Hardware Changes All jobs engineered by PSCs based on customer requirements and preferences should not be redesigned by the Field Services Organization (FSO) without approval by the PSC/MBO. If changes are required, a change order must be issued to ensure correct billing. 1-10 Planning Planning The following information will help you design a uniform wiring plan with growth potential. The plan is simple, flexible, easy to administer, and reasonable in cost. Job Aids Blueprints (floor plans) are important when planning, designing, and installing station wiring. The floor plans (Figure 1-5) provide a complete view of all conduit and other cabling facilities in the building. These facilities should be considered when planning site or satellite locations and cabling. Voice Terminals The number of information outlets to be installed per voice terminal location is determined by customer requirements. It may be advantageous to install any additional information outlets required for future growth or voice terminal rearrangements during the initial installation. To begin designing the station wiring, show the following information on the floor plan(s): ● Location of each information outlet and associated voice terminal type if known (analog, hybrid, or digital) ● Any associated voice terminal adjuncts or modules and the required powering arrangements. 1-11 CHAPTER 1.

Sample Floor Plan With Voice Terminal Locations Marked 1-12 Planning Site or Satellite Closets When determining the location of site or satellite closets, use the following information as a guide. Show the locations on the floor plan. a. Keep the number of locations to a minimum. b. Centrally locate the site or satellite closets among the information outlets to minimize station wiring distances. c. Site or satellite closets must be easily accessible and contain enough ac power receptacles to serve the equipment that will be located there. Voice terminals equipped with adjuncts that require power can be remotely powered from: ● a site or satellite location ● from the main equipment room ● information outlets. d. The distance between the power supply and the voice terminal cannot exceed 250 feet of 24-gauge wire. e. Locks should be provided for the site or satellite closet doors to prevent tampering with the equipment. Cabling Facilities The method of riser cable distribution between the main equipment room and site or satellite closets is usually determined by the type of cabling facilities (riser closets, conduit size, cabling shafts, etc.) in the building (Figure 1-6). a. The preferred arrangement is to have individual cables supply each site or satellite closet. b. A second method is to have one or two large cables supply all the site or satellite closets. This requires that smaller cables be installed between the main riser cable and the site or satellite closet. These smaller cables are then spliced into the main cable. Determine the type of cabling required and mark the type and routing on the floor plan. Also, show any additional cabling facilities required for riser and terminal cabling. 1-13 CHAPTER 1. INTRODUCTION PREFERRED ACCEPTABLE INDIVIDUAL 100-PAIR RISER CABLES MAIN RISER CABLE WITH SMALLER CABLES SPLICED TO IT TWO POSSIBLE WAYS TO PLACE RISER CABLE CAUTION: THE UNIFORM WIRING PLAN SHOULD NOT CONTAIN ANY BRIDGE TAPS (AN UNUSED CABLE PAIR CONNECTED TO A WORKING CABLE OR THE CONTINUATION OF A WORKING PAIR PAST THE POINT AT WHICH A TERMINAL HAS BEEN CONNECTED).

Block Diagram of System 75 or 75 XE Installation 2-2 110-Type Hardware Description 110-Type Hardware Description The 110-type hardware consists of connectorized or field-terminated terminal blocks in 100-, 300-, and 900-pair sizes. The 110-type terminal blocks consist of the following parts: ● 110-type wiring blocks ● Index strips ● 3-, 4-, and 5-pair connecting blocks. 110-Type Wiring Blocks The 110-type wiring block (Figure 2-2) is a plastic wiring block equipped with permanently attached index strips. DESIGNATION INSERT WIRING BLOCK TERM NO. 1 INDEX STRIP TERM NO. 50 Figure 2-2. 110-Type Wiring Block 2-3 CHAPTER 2. HARDWARE (66/110-Type) Index Strips and Connecting Blocks The index strips (Figure 2-3) are slotted rows that provide space to terminate 25-pair cables. The wires are placed in the slots in the index strip. The standard termination for a 25-pair cable is shown in Table 2-A. CABLE IS TERMINATED IN 25-PAIR INDEX STRIP 3-PAIR CONNECTING BLOCKS 110-TYPE WIRING BLOCK (TOP VIEW) TERMINATION POINTS FOR CROSS-CONNECTIONS (JUMPERS OR PATCH CORDS) 4-PAIR CONNECTING BLOCK Figure 2-3. 110-Type Index Strip With Connecting Blocks The connecting blocks (Figure 2-3) are equipped with clips that slice the insulation of the wires when the connecting block is pushed onto the index strip. The top of the connecting blocks are used for cross-connections. When a wire is punched onto the top of the connecting block, it makes a connection, through the connecting block, to the wire in the index strip. The connecting blocks come in 3-, 4-, and 5-pair blocks. When 3- or 4-pair connecting blocks are used, the last connecting block on each index strip must be one pair larger to complete the 25-pairs. The ordering codes determine the type of connecting blocks received with a terminal block. The 110-type wiring blocks allow for individual 3- and 4-pair connecting blocks to be disconnected for testing without disturbing adjacent circuits. 2-4 110-Type Hardware Description Table 2-A. 25-Pair Cable Termination on a 110-Type Wiring Block/66-Type Connecting Block 25-Pair Cable Connector Pin Numbers 26 1 27 2 28 3 29 4 30 5 31 6 32 7 33 8 34 9 35 10 Pair 1 2 3 4 5 6 7 8 9 10 Color W-BL BL-W W-O O-W W-G G-W W-BR BR-W W-S S-W R-BL BL-R R-O O-R R-G G-R R-BR BR-R R-S S-R 110-Type 66-Type Wiring/Conn Block Terminals 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 2-5 CHAPTER 2.

The 110P-type hardware uses patch cords to make cross-connections. This allows the customer to make cross-connections. The 110A-type hardware uses individual jumper wires for cross-connections. For this reason, the 110A-type hardware is not intended for customer usage because it requires technically skilled personnel to make cross-connections. The 110A- and 110P-type hardware should not be mixed together in the same room. 110A-Type Hardware The 110A-type hardware consists of a 100- or 300-pair wiring block and the associated connecting blocks. The 100-pair wiring blocks (Figure 2-4) are arranged for field termination. The 300-pair wiring blocks (Figure 2-5) come in both field-terminated and connectorized (with 6-foot cable stubs) types. 2-7 CHAPTER 2.

EQUIPMENT ROOM DESIGN CHAPTER 3. EQUIPMENT ROOM DESIGN General The System 75—System Description (555-200-200) or System 75 XE—System Description (555-201-200) provides equipment room specifications for temperature, humidity, air purity, lighting levels, and grounding. They also provide information on the floor and wall space required for the switch and the associated peripheral equipment that is to be installed in the equipment room. For completeness, some of the information contained in these documents is repeated in this guide. Hardware Equipment Room Applications In the equipment room, the 66-type/110-type hardware is used for the cross-connect field which consists of a trunk/auxiliary field and a distribution field (port, auxiliary, and station). Trunk/Auxiliary Field The trunk/auxiliary field contains three distinct cross-connect areas: ● The green field terminates the network interface leads (from the CO) and provides the terminals to cross-connect the CO leads to the purple or yellow fields as required. A single row of the 66-type connecting block/110-type terminal block can terminate twenty-four 1-pair, eight 3-pair, or twelve 2-pair trunks. ● The purple field terminates the trunk circuits from the switch with WP-90929, List 1 or 3 (110-type terminal block) or WP-90929, List 2 or 4 (66-type connecting block) concentrator cables. Also, 25-pair cables can be used to terminate trunk circuits from the switch with each trunk circuit pack connecting to one 25-pair row of the 66-type connecting bIock/110-type terminal block. Each 66-type connecting block/110-type terminal block row can terminate twenty-four 1-pair, eight 3-pair, or twelve 2-pair trunks. ● The yellow field provides cross-connection terminals for all miscellaneous leads from the switch, such as alarm monitors, emergency transfer relay power, attendant console power, and 3-1 CHAPTER 3. EQUIPMENT ROOM DESIGN Initialization and Administration System (INADS) trunk. This field is also used for emergency transfer wiring, applications processor (AP) alarms, paging equipment, music sources, etc. Trunk/Auxiliary Field (110-Type Hardware Only) Figure 3-1 shows two typical 300-pair terminal block configurations of 110-type hardware arranged for use in the trunk/auxiliary field. One 300-pair terminal block will terminate 96 three-pair circuits and two 300-pair terminal blocks will terminate 192 three-pair circuits. 188D2 BACKBOARD GREEN FILL GREEN FILL PURPLE FILL YELLOW FILL YELLOW FILL PURPLE FILL YELLOW FILL CAPACITY = 96 3-PAIR CIRCUITS CAPACITY = 192 3-PAIR CIRCUITS Figure 3-1. 300-Pair Trunk/Auxiliary Field Arrangements The 110-type terminal blocks that can be used in the trunk/auxiliary field are the: ● 3-2 110AC1-300STM/6 which has six stub cables that exit from the top of the terminal block. Each cable stub is 6-feet long and equipped with a 50-pin male connector. Hardware Equipment Room Applications ● 110AC1-300STF/6 which has six stub cables that exit from the top of the terminal block.

Each cable stub is 6-feet long and equipped with a 50-pin female connector. Figure 3-2 shows two typical 900-pair terminal block configurations of 110-type hardware arranged for use in the trunk/auxiliary field.

The connectors are mounted at the bottom of the terminal block. This allows for easy cable routing to the floor and/or the cable slack manager as required. 3-3 CHAPTER 3. EQUIPMENT ROOM DESIGN ● 110PC1-900CT which is equipped with 36 female 50-pin connectors. The connectors are mounted at the top of the terminal block. This can be used if cable routing from the top is desirable. Distribution Field The distribution field contains four distinct cross-connect areas: ● The purple field (port field) terminates 25-pair cables from the switch. Each line circuit pack connects to one 66-type connecting block or to one 25-pair row of the 110-type terminal block. One 25-pair cable is required for each line circuit pack. Note: This is the case except for the 16 port analog line circuit pack and the MET line circuit pack. The 16-port analog line circuit pack requires an adapter cable to connect from one connector on the switch to two 25-pair connectors on a 66-type connecting block/110-type terminal block. Two MET line circuit packs require a concentrator cable to connect from two connectors on the switch to one 25-pair connector on a 66-type connecting block/110-type terminal block. 3-4 ● The yellow field (auxiliary field) terminates all 25-pair cables from the auxiliary cabinet and the AP. The yellow field is located in the lower right-hand corner of the distribution field. ● The white field (station field) terminates the station wiring. The white field indicates 3-pair station circuits (eight circuits per 25-pair cable) that are routed through a satellite closet. ● The blue field (station field) also terminates station wiring. The blue field indicates 3- and/or 4-pair station circuits (eight or six circuits, respectively, per 25-pair cable). The fourth pair, of the 4-pair station circuit provides adjunct power from the cross-connect field on an as-needed basis to terminals within 250 feet (wire length) of the cross-connect field.

It is possible that only a few 66-type connecting blocks will be required in the trunk/auxiliary field for the green and yellow fields. For this reason, if 157B connecting blocks mounted on a purple 183-type or 166-type backboard is used as the trunk/auxiliary field, then some of the extra connecting blocks in the purple field can be used as the green and yellow fields to save ordering extra backboards and connecting blocks. When this is done, the green and yellow fields should be clearly identified to avoid confusion. When white backboards are required for cross-connections with a satellite closet, they must be ordered from an outside vendor. If a blue backboard is used for these cross-connections, then the part of the blue field that is functionally used as the white field, should be clearly identified. 3-11 CHAPTER 3.

Typical Cross-Connect Field Installation using 66-Type Connecting Blocks Wall Space Requirements Approximately 8 inches of horizontal wall space is required for each column of sneak fuse panels. Horizontal wall space must also be provided for emergency transfer units. 3-20 Typical System Equipment Room Floor Plans Wall Space Requirements for 110-Type Hardware The trunk/auxiliary field and the distribution field are mounted on the same wall. Each 110P-type terminal block is 8-1/2 inches wide. Vertical patch cord troughs are 5-5/16 inches wide and horizontal patch cord troughs are 23 inches wide. Each 110A-type terminal block is 10-13/16 inches wide; however, no horizontal patch cord troughs are used and the blocks are shorter than 110P-type terminal blocks. This allows the 110A-type terminal blocks to be stacked. Therefore, the 110A-type hardware requires less space than the 110P-type hardware on a per-station basis. Wall Space Requirements for 66-Type Hardware The trunk/auxiliary field and the distribution field are mounted on the same wall. If the 66-type connecting blocks are being mounted directly on a wall, the space requirements of a 183-type backboard should be used to figure the amount of wall space required for the connecting blocks. This method allows enough space between the connecting blocks for jumper wires and cable connections. The 183A-type backboard mounts four 66-type connecting blocks and is 8-1/2 inches wide and 20 inches tall. The 183B-type backboard mounts eight 66-type connecting blocks, and is 17 inches wide and 20 inches tall. When multiple mountings are required, each 166-type mounting is 17 inches wide and 20 inches tall, and each 154A-type mounting is 8-1/2 inches wide and 20 inches tall. The 187B1 backboard, equipped with pegs, is 17 inches wide and 6-1/2 inches tall. Equipment Requirements Cable Slack Manager Requirements A cable slack manager is 32 inches wide. The quantity of cable slack managers required is determined by dividing the total length of the cross-connect field (in inches) by 32. A partial number of .4 or less should be rounded down, and a partial number of .5 or more should be 3-21 CHAPTER 3. EQUIPMENT ROOM DESIGN rounded up (for example: 2.4 = 2 cable slack managers and 2.5 = 3 cable slack managers required). 110-Type Hardware and Patch Cord Requirements Table 3-D lists the amount of 110-type hardware required to provide 1-, 2-, 3-, or 4-pair distribution for the station wiring. The 110-type terminal blocks are available in various sizes and the number of stations connected to each block depends on the number of pairs that are run per station.

Procedures are provided for installing the following: ● Cross-connect field ● Cable slack managers ● Labels for cross-connect field ● Sneak fuse panels. Installing the Cross-Connect Field The preferred cross-connect field location is directly behind the switch cabinet. Wall Mounting 110A-Type Terminal Blocks The 110A-type hardware can be stacked in almost any arrangement at any height or location on the wall. One arrangement is shown in Figure 3-10. The distance between the mounting screw holes on the terminal blocks is 10-13/16 inches. If a vertical patch cord trough is to used, the distance between the mounting screw holes is 5-5/16 inches. Wall Mounting 110P-Type Terminal Blocks The first terminal block of the trunk/auxiliary field is aligned with the left side of the switch cabinet (Figures 3-11 or 3-12). This arrangement allows for growth on the right side of the cross-connect field. To install the cross-connect field, proceed as follows: 1. If 300-pair terminal blocks are to be installed, draw a level horizontal line on the wall 47-1/2 inches above the floor (Figure 3-14). If 900-pair terminal blocks are to be mounted, draw a level horizontal line on the wall 23 inches above the floor (Figure 3-15). 3-25 CHAPTER 3.

Frame Mounting 110P-Type Terminal Blocks The 900-pair 110P-type terminal blocks and the associated patch cord troughs can also be mounted on a free-standing, floor-mounted 1110A2 apparatus mounting frame (Figure 3-16). Each 1110A2 apparatus mounting frame provides the space to mount five terminal blocks/patch cord troughs on each side of the frame. A cable support structure, apparatus mounting 1110C1, mounts directly on top of the 1110A2 apparatus mounting frame and provides support for all cables routed to and from the frame. 3-28 Equipment Room Hardware And Cabling Installation NO. 1110C1 APPARATUS MOUNTING NO. 111OA2 APPARATUS MOUNTING 88.50" 76.00" 43.50" Figure 3-16. 1110A2 and 1110C1 Apparatus Mountings 3-29 CHAPTER 3.

This arrangement allows for orderly growth toward the right side of the cross-connect field. The connectorized 66-type connecting blocks are factory wired for cable routing from the top so that the cable connector will align with the connector on the connecting block. If cable routing from the bottom is desired, then the connector on the connecting block must be removed and rotated 180 degrees. Then, the connector must be relocated in the previously unoccupied hole because the connecting block leads are not long enough to reach the hole where the connector was previously mounted. The VELCRO® cable retainer must also be relocated. To install the cross-connect field, proceed as follows: 1. Draw a level horizontal line on the wall 12 inches above the floor (Figure 3-17). * Registered trademark of VELCRO U.S.A.

Move the backboard/connecting block into place and fasten it to the wall with 3/4-inch No. 12 wood screws. 5. The next backboard/connecting block can be mounted to the right or above the one just installed, depending on space requirements. 3-31 CHAPTER 3. EQUIPMENT ROOM DESIGN Repeat Steps 2, 3 and 4 until each backboard or connecting block has been installed. Note: The 66-type connecting blocks should not be installed more than 78-1/2 inches above the floor. Installing Cable Slack Managers To install the cable slack managers (Figure 2-17), proceed as follows: 1. Place the Z113A cable slack manager against the wall under the cross-connect field (Figure 3-9), aligning the left side of the cable slack manager with the first terminal block of the trunk/auxiliary field. 2. Place the next cable slack manager beside the previously installed cable slack manager. Align the tabs and interlocks, and snap the cable slack managers together. 3. Repeat Step 2 until all cable slack managers are installed. Note: Nine holes (¼-inch) are provided in a cable slack manager base in the event earthquake mounting is required. Also, if a cable slack manager base is mounted on an uneven floor, shims may be required to level it and insure proper fit of the covers. Holes are provided in the sides of the base for bolting cable slack managers together. Bolts and shims must be obtained locally. Labeling the Cross-Connect Field Labeling 110-Type Terminal Blocks Figure 3-18 shows the graphic symbols used (instead of words) on labels for the switch, cross-connections, information outlets, and cables for the system.

Cable Routing Through Cable Slack Manager—SingleCabinet Installation (Using 66-Type Connecting Blocks With Cables Routed From Bottom of Cross-Connect Field) 3-72 Equipment Room Hardware And Cabling Installation Routing Cables From Cabinet to Cross-Connect Field The following guidelines should be followed when routing cables from the cabinet to the cross-connect field. ● When cable routing is to the top/bottom of the cross-connect field, each port cable is connected at the cabinet and then routed along the front trough of the cable slack manager to the connecting/terminal block where the cable is to be terminated. ● Enough slack must be left at the cabinet end of the cable to allow for proper dressing of the cables (Figure 3-50). ● Route the cable from the cabinet to the wall. Place the cable beside one of the rows of columns in the cable slack manager (see Note). Note: Retainers mounted on the columns keep the cable from protruding above the top of the base of the cable slack manager. ● Determine the length of the cable required to reach from the cable slack manager to the assigned connecting/terminal block. ● The cable must be supported on the wall using D rings. ● Cable slack is stored by coiling the cable around the columns in the cable slack manager. The first run should always go across the full length of the five columns in the cable slack manager. ● Connect the cable to the assigned connecting/terminal block. 3-73 CHAPTER 3.

EQUIPMENT ROOM DESIGN Installing Coupled Bonding Conductor (CBC) Grounding A CBC must be tie-wrapped to all trunk cables. The CBC connects the cabinet single-point ground block to the approved ground located nearest the telephone company owned protector block at the building entrance facility (Figure 3-59). Note: The CBC is a conductor that is connected to ground and run adjacent to the pairs in an inside wiring cable. The mutual coupling between the bonding conductor and the cable pairs reduces potential differences in terminating equipment. The conductor consists of a No. 10 AWG wire that is tie-wrapped to the inside wiring cable. APPROVED GROUNDS An approved ground is an acceptable medium for grounding the building entrance protector, entrance cable shield, or single-point ground of electronic PBX equipment. If more than one type of approved ground is available on the premises, the grounds must be bonded together as required in Section 250-81 of the National Electrical Code. Metal Frame of the Building — the metal frame of the building where it is effectively grounded by one of the following grounds: acceptable metallic water pipe, concrete encased ground, or a ground ring. Acceptable Water Pipe — a metal underground water pipe, at least 1/2 inch in diameter, in direct contact with the earth for at least 10 feet. The pipe must be electrically continuous (or made electrically continuous by bonding around insulated joints, plastic pipe, or plastic water meters) to the point where the protector ground wire is connected. A metallic underground water pipe must be supplemented by the metal frame of the building, a concrete encased ground, or a ground ring. If these grounds are not available, the water pipe ground can be supplemented by one of the following types of grounds: ● Metal underground gas piping system—an electrically continuous metal underground gas piping system that is uninterrupted with insulating sections or joints and without an outer nonconductive coating ● Other local metal underground systems or structures—local underground structures such as tanks and piping systems 3-86 Equipment Room Hardware And Cabling Installation ● Rod and pipe electrodes—a 5/8 inch (solid rod) or 3/4 inch (conduit or pipe) electrode driven to a minimum depth of 8 feet ● Plate electrodes—expose a minimum of 2 square feet of metallic surface to the exterior soil. Concrete Encased Ground — an electrode encased by at least 2 inches of concrete and located within and near the bottom of a concrete foundation or footing in direct contact with the earth. The electrode must be at least 20 feet of one or more steel reinforcing bars or rods 1/2 inch in diameter, or at least 20 feet of bare, solid copper, No. 4 AWG wire. Ground Ring — a buried ground that encircles a building or structure at a depth of at least 2-1/2 feet below the earth’s surface. The ground ring must be at least 20 feet of No. 2 AWG, bare, copper wire. APPROVED FLOOR GROUNDS Approved floor grounds are those grounds on the floor of a high-rise building suitable for connection to the ground terminal in the riser closet and to the PBX equipment single-point ground terminal. Such grounds may be one of the following: ● Building steel ● The grounding conductor for the secondary side of the power transformer feeding the floor ● Metallic water pipes ● Power feed metallic conduit supplying panel boards on the floor ● A grounding point specifically provided in the building for the purpose. 3-87 CHAPTER 3. EQUIPMENT ROOM DESIGN DANGER If the approved ground or approved floor ground can only be accessed inside a dedicated power equipment room, then connections to this ground should be made by a licensed electrician 10 GAUGE CBC TRUNK CIRCUITS SINGLE-POINT GROUND BLOCK CABLE ENTRANCE TERMINAL LIGHTNING SURGE PROTECTOR APPROVED GROUND Figure 3-59. Installing the Coupled Bonding Conductor 3-88 Equipment Room Hardware And Cabling Installation Installing Connector Cables Between Switch Cabinet and the Cross-Connect Field Before starting the following procedure, refer to the heading Routing Cables From Cabinet to Cross-Connect Field in this chapter. Also, all purple labels should have been previously installed as described in this chapter under the heading Labeling the Cross-Connect Field. 1. Install "D" rings on the wall between the cable slack manager and the terminal/connecting blocks mounted on the cross-connect field. 2. Install a self-sticking port label on the back of each connector on the connector cable (Figure 3-43). Note: Labels should be positioned so they will not be obscured by the cabinet connector retainers. 3. At the rear of the cabinet, connect one end of the connector cable to the assigned connector. 4. Dress the cable down the back of the cabinet, and through the cable slack manager to the cross-connect field. 5. At the cross-connect field, connect the other end of the cable to the assigned terminal/connecting block connector. 6. Store the cable slack in the cable slack manager. 7. Repeat previous Steps 2 through 6 until all cables are installed. Installing Connector Cables Between Auxiliary Cabinet and Cross-Connect Field Auxiliary equipment that connects to the cross-connect field can be mounted inside the auxiliary cabinet. The equipment connects to an ED-1E1443-10 (Group 1) intraconnection panel mounted in the auxiliary cabinet. This intraconnection panel consists of a 110-type 100-pair wiring block mounted inside the cabinet. Auxiliary equipment is connected to the 110-type wiring block. The wiring block is prewired to four 25-pair female connectors mounted on the outside rear skin of the cabinet. 3-89 CHAPTER 3. EQUIPMENT ROOM DESIGN Install connector cables between the auxiliary cabinet and cross-connect field as follows; 1. Install "D" rings on the wall between the cable slack manager and the terminal/connecting blocks mounted on the cross-connect field. 2. Install a self-sticking port label on the back of each connector on the B25A connector cable (Figure 3-43). Note: Labels should be positioned so they will not be obscured by the cabinet connector retainers. 3. At the rear of the auxiliary cabinet, connect one end of the connector cable to the assigned connector. 4. Dress the cable down the back of the cabinet, and through the cable slack manager to the cross-connect field. 5. At the cross-connect field, connect the other end of the cable to the assigned terminal/connecting block connector. 6. Store the cable slack in the cable slack manager. 7. Repeat previous Steps 2 through 6 until all cables are instaIled. Details for installing the equipment and making the connections to the cross-connect field are included in Chapter. Station Wiring Design General The following hardware and cabling is used in the station wiring design: ● Information outlets ● Station Cables ● Closets — Site locations ● ● 3-90 — Satellite locations Adapters. Labels Station Wiring Design A brief description of each of the above listed items follows. The station wiring labels and their use are described in Chapter 4. Ordering information is not provided for station cables and information outlets. The ordering information for this equipment is available in the Premises Distribution System Equipment and Supplies Catalog. Information Outlets Information Outlets are 8-pin modular wall jacks. Most of the outlets are wired with push-on connections. Information outlets are also available that connect to a double modular plug-ended 4-pair station cable run from the cross-connect field, a site/satellite location, or an adapter. Station Cables For clarity in describing the wiring in this guide, station cable is either 25-pair cable, multiple 25-pair cable, or 4-pair D-inside wire (DIW) run from the equipment room, a site/satellite location, or an adapter to the information outlets. The following types of station cable are available. ● Connectorized 25-pair station cable—This cable is used between the equipment room and the site/satellite locations or adapters. For 110-type hardware, use an A25D cable (male to male) between the equipment room and a satellite closet, and use a B25A cable (male to female) between the equipment room and a site closet or adapter. For 66-type hardware, use an A25B cable (female to female) between the equipment room and a satellite/site closet or adapter. The A25B cable is available with connectors on each end (double-ended), and also with a connector on only one end (single-ended). Use the single-ended cable when the leads are punched down on the connecting blocks. ● Connectorized multiple 25-pair station cable—This cable can be used between the equipment room and the site/satellite locations or adapters. This cable consists of individually sheathed 25-pair cables with a factory-installed 25-pair connector on each end. For 110-type hardware, use a male to female cable to connect between the equipment room and a site location or adapter, and use a male to male cable to connect between the equipment room and a satellite location. For 66-type hardware, use a female to female cable to connect between the equipment room and a 3-91 CHAPTER 3. EQUIPMENT ROOM DESIGN site/satellite location or adapter. Staggered-finger cables are recommended for all multiple 25-pair station cables. Staggered-finger cables are available in both double-ended and single-ended types. ● Bulk Cable—This cable is the same as the connectorized 25-pair cable or multiple 25-pair cable; however, the bulk cable is not equipped with connectors. Use this cable between the equipment room and satellite closets when both are equipped with punch-down type terminal/connecting blocks. ● Nonconnectorized 4-pair station cable—Use this cable when 4-pair station cables are to be field-terminated on the 110-type terminal blocks/66-type connecting blocks in the equipment room or satellite closet and the information outlets require push-on connections. ● Single modular plug-ended 4-pair station cable(Figure 3-60)—Use this cable between adapters and information outlets that require push-on connections. It can also be used when 4-pair station cables are field-terminated on the 110-type terminal blocks/66-type connecting blocks in the equipment room or satellite closet and modularly connected to information outlets. The station cables are available in the following lengths: ● ● ● ● ● ● ● ● 3-92 10 feet 25 feet 50 feet 75 feet 100 feet 150 feet 200 feet. Double modular plug-ended 4-pair station cable—Use this cable to provide nonstandard length runs between adapters and information outlets with push-on connections. It can also be used between adapters and modularly connected information outlets. It is available in the same lengths as the single modular plug-ended cable (see Note). Station Wiring Design MODULAR PLUG Figure 3-60. 4-Pair Single Modular Plug-Ended Station Cable Note: If more than 200 feet of 4-pair station cable is required, a 451A in-line adapter (double-ended modular female connector) is attached to the cable and a second 4-pair cable of the required length is plugged into the adapter (Figure 3-61). 451A ADAPTER ORDERING INFORMATION Color Comcode Gray 103 942 272 Ivory 103 786 240 3-93 CHAPTER 3.

The station cable circuits from the equipment room cross-connect field are 3-pair. The hardware at the equipment room has been described previously. At the satellite location, 4-pair circuits run to the information outlets. The hardware used at the satellite location is 110-type terminal blocks/66-type connecting blocks. Satellite Locations Using 110-Type Hardware Each terminal block has a 3-pair (white field) and a 4-pair (blue field) located on the same terminal block. The 110A-type terminal block that can be used in the satellite closet is the 110AE1-75FT. It must be field-terminated to both the white and blue fields. The 300-pair 110P-type terminal blocks that can be used in the satellite closet are the: LI 110PE1-300CT—connectorized on both the white and blue fields ● 110PE1-300CT/FT—connectorized field-terminated on the blue field on the white field and ● 110PE1-300FT—field-terminated on both the white and blue fields. The 900-pair 110P-type terminal blocks that can be used in the satellite closet are the: ● 110PE1-900CT/FT—connectorized field-terminated on the blue field on the white field and ● 110PE1-900FT—field-terminated on both the white and blue fields. 3-97 CHAPTER 3. EQUIPMENT ROOM DESIGN Satellite Locations Using 66-Type Hardware The 3-pair station circuits from the equipment room are terminated on a 66-type connecting block in the satellite closet white field, and then cross-connected to a 66-type connecting block in the blue field. The 4-pair station circuits from the information outlets are terminated on the satellite closet blue field. The following 66-type connecting blocks can be used in a satellite closet; ● 66M1-50 connecting block ● 157B connecting block ● 154A-type backboard ● 166A-type bakcboard Station Circuit Distribution From Equipment Room The following information explains the station circuit distribution from the equipment room to the information outlets for new wiring installations. Connection diagrams are provided to show the options for running and connecting the station cables. If most of the telephones/voice terminals that require remote powering are within 250 feet of the equipment room, 4-pair station circuits are run from the equipment room to the information outlets. If this is not the case, or if the customer requires 2-point administration, 3-pair station circuits are run from the equipment room to satellite locations. Then, the 4-pair station circuits are run from the satellite locations to the information outlets. 4-Pair Station Circuits Four-pair circuits can be run directly from an equipment room cross-connect field to a 258A or BR2580A adapter as shown in Figure 3-64. The 4-pair station cables connect the adapter to the information outlets. 3-98 Station Wiring Design Figure 3-64. 4-Pair Circuit Distribution and Connectivity From Equipment Room Cross-Connect Field 3-99 CHAPTER 3. EQUIPMENT ROOM DESIGN The 4-pair station cables can be run, directly from the equipment room to the information outlets if 4-pair terminal blocks are used in the distribution field (Figure 3-65). The station cables must be field-terminated on the 110-type terminal blocks/66-type connecting blocks. If 110-type terminal blocks are used with a modular plug-ended station cable, an adapter can be connected directly to the 110-type terminal block connectors (Figure 3-66). 11O-TYPE TERMINAL BLOCK 66-TYPE CONNECTING BLOCK AT STATION SIDE OF CROSS-CONNECT FIELD OR SATELLITE LOCATION INFORMATION OUTLET 4-PAIR CIRCUITS 4-PAIR CIRCUIT BLUE FIELD STATION CABLE (DIW) PUNCH-DOWN CONNECTION Figure 3-65. 4-Pair Home Run to Equipment Room or Satellite Location 3-100 Station Wiring Design PART OF EQUIPMENT ROOM CROSS-CONNECT FIELD (110-TYPE TERMINAL BLOCKS) 4-PAIR 3-PAIR CONNECTING CONNECTING BLOCKS BLOCKS 258A OR BR2580A ADAPTER INFORMATION OUTLET 4-PAIR CIRCUIT TO SWITCH PURPLE FIELD BLUE 110P6A FIELD PATCH CORD OR JUMPERS STATION CABLE (DIW) 4-PAIR CIRCUITS Figure 3-66.

The floor plans must also show a complete overview of all conduit and cabling facilities in the building. Locating Satellites and Sites Use the following information when determining site, satellite, or adapter locations. a. Keep the number of locations to a minimum. b . To minimize the station wiring distances, centrally locate the sites/satellites, or adapters among the information outlets. c . Site/satellite locations must be easily accessible and contain ac power receptacles. Adapter Requirements One 258A/BR2580A adapter is required for each 25-pair station cable containing 4-pair station circuits. One 356A adapter is required for each 25-pair station cable containing 3-pair station circuits. Hardware Requirements Hardware requirements are the same as for the equipment room. Sizing 4-Pair Station Cables Use the scale of the floor plan to determine the approximate length of the station cables required per the standard Premises Distribution Systems wiring concepts. 3-107 CHAPTER 3. EQUIPMENT ROOM DESIGN Sizing 25-Pair and Multiple 25-Pair Station Cables Use the scale of the floor plan to determine the approximate length of each 25-pair station cable. The 25-pair station cables must be selected and properly sized to make maximum use of the hardware at the equipment room or satellite location. When using 110-type hardware, use 25-pair B25A cables to connect adapters directly to the equipment room cross-connect field or satellite location. Staggered-finger cables, equipped with factory-installed 25-pair connectors at both ends (male to female), are recommended for use when multiple 25-pair cables are to be used between the equipment room or satellite location and the adapters. B25A cables are required at the equipment room or satellite location to connect the staggered-finger cables to the 110-type terminal blocks. When using 66-type hardware, use 25-pair A25B cables to connect adapters directly to the equipment room cross-connect field or satellite location. Staggered-finger 25-pair cables (double- or single-ended), are recommended for use when multiple 25-pair cables are to be used between the equipment room or satellite location and the adapters. B25A cables are required at the equipment room or satellite location to connect the double-ended (female to female) staggered-finger cables to the 66-type connecting blocks. Use the following information to determine the cable size (cable pairs) required for either 3-pair or 4-pair circuits. Note the length and size on the floor plan to aid in the ordering and installation of the station cables. 3-Pair Station Cable Circuits To determine the size of station cables containing 3-pair circuits, multiply the number of 3-pair circuits required at the satellite location by 3.5. Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size. This will provide additional pairs for growth and compensate for the fact that every twenty-fifth pair in a cable is not used. 3-108 Station Wiring Design 4-Pair Station Cable Circuits To determine the size of station cables containing 4-pair circuits, find out how many information outlets are served by the equipment room cross-connect field or satellite location cross-connect field. Multiply the number of information outlets by 4 (see Note). Then, using the minimum size cable requirement, round up the cable size requirement to the next highest available cable bundle size. Note: This formula may not compensate for the unused twenty-fifth pair in all cases. If not, you must allow for it. 3-109 CHAPTER 4.

Removing Patch Cords/Jumper Wires When it is necessary to remove a patch cord/jumper wire because a telephone/voice terminal is being removed, disconnect the telephone/voice terminal at the information outlet. Then, remove the patch cord/jumper wire from the cross-connect field. This gives a visual indication of the available terminal/connecting block terminals associated with port and station jacks. Do not leave a partially or totally disconnected patch cord/jumper wire intermingled with the remaining patch cords/jumper wires. When it is necessary to rearrange patch cords/jumper wires because of telephone/voice terminal moves, remove the patch cord/jumper wire and reinstall it even if only one end of the cross-connection is affected. This reduces entanglement and helps to assure a neat appearance. To remove a patch cord/jumper wire, proceed as follows: 1. On the Port Assignment Record(Figure 4-11), locate the terminal/connecting block associated with the jack assignments at the purple and white or blue fields. 2. At the purple field, disconnect the patch cord/jumper wire (see Note). Note: An impact tool or 724A tool (for 66-type hardware only) is required when removing jumper wires. 3. Lift the patch cord/jumper wire upward, taking up slack, until the patch cord/jumper wire can be located by its movement in the patch cord trough/187B1 backboard. 4. Trace the other end to its connection point at the blue or white field and disconnect the patch cord/jumper wire. 5. Remove the patch cord/jumper wire from the patch cord trough/187B1 backboard. 6. Update the Port Assignment Record (Figure 4-11). 4-22 Patch Cord/Jumper Installation And Administration 7. Update system translations. Installing and Removing Power Adapter Cords The power adapter cords are installed as described previously in the Adjunct Powering section of this chapter (Figure 4-8). The power adapter cords can be used only with the 4-pair station circuit terminal/connecting blocks. The telephone/voice terminal and adjunct must be installed before installing the power adapter cord and patch cord/jumper wire. To remove a power adapter cord, proceed as follows: 1 . On the Port Assignment Record (Figure 4-11), locate the station jack number for the telephone/voice terminal receiving remote power. 2 . Unplug the power adapter cord at the power supply. 3 . Locate the power adapter cord plug/leads on the 110-type terminal block/66-type connecting block (blue field). 4. Disconnect the power adapter cord/leads from the terminal/connecting block. 5 . Remove the power adapter cord from the patch cord troughs/187B1 backboards. 6 . Update the Port Assignment Record. Satellite Locations The guidelines for installing and removing patch cords, jumper wires, and power adapter cords at the equipment room cross-connect field should be followed at a satellite location cross-conect field. The cross-connects should be made between the white field (equipment room side) and the blue field (station side). 1-Point Administration For 1-point administration (Figure 4-12), the patch cords/jumper wires are connected between purple field terminal/connecting blocks and white field terminal/connecting blocks at the equipment room. The patch cords/jumper wires are connected between identically numbered 4-23 CHAPTER 4. STATION WIRING white field terminal/connecting blocks (equipment room side) and blue field terminal/connecting blocks (station side). 2-Point Administration For 2-point administration (Figure 4-13), the patch cords/jumper wires are connected between purple field terminal/connecting blocks and white field terminal/connecting blocks at the equipment room. At the satellite location, patch cords/jumper wires are connected between the white field terminal/connecting blocks (equipment room side) and blue field terminal/connecting blocks (station side) as specified on the Port Assignment Record. Update the Port Assignment Record for all administrative changes at a satellite location. Miscellaneous Wiring Installation Installing System Access Terminal (SAT) The SAT is connected to the TERM connector that is located on the rear of the control carrier.

For V2 or V3 systems only, the customer’s asynchronous data terminals can be connected through a Z3A ADU to a TN726 data line circuit pack (Figure 5-24). Normally, the ADU is powered from the connected data terminal. The ADU can also be remotely or locally powered using a 2012D transformer equipped with a 248B adapter. ADUs connected to receive-only printers always require external power. The need for external power must be determined experimentally for ADUs connected to other devices. For details on ADU installation, refer to the Z3A Asynchronous Data Unit User’s Manual (555-401-701). Installation 1. Determine ADU port assignment from Data Module Form: EXAMPLE: Port Number B Carrier 02 Slot 01 Circuit 2. Connect the RS-232 plug on the ADU to the data terminal. 3. Connect a 4-pair line cord (modular plug on both ends) from the information outlet to the ADU (Figure 5-24). 4. Install patch cord/jumper wires at cross-connect field. 5. Administer per AT&T System 75 and System 75 XE—Implementation (555-200-651) and AT&T System 75 and System 75 XE—Administration (555-200-500). Installing SMDR Interface The interface between the switch and SMDR is through a PDM, trunk data module (TDM), or 212-type modem. For connections between the switch and the PDM or TDM, refer to the section on installing PDMs (Figures 5-21 and 5-22). Administer per AT&T System 75 and System 75 5-45 CHAPTER 5. AUXILIARY EQUIPMENT INSTALLATION XE—Implementation (555-200-651) and AT&T System 75 and System 75 XE—Administration (555-200-500). The connection between the switch and the 212-type modem is the same as for external ringing (Figure 4-39). When a 212-type modem is used, a TN758 pooled modem circuit pack must be provided. One of the pooled modem’s conversion resources is dedicated to the SMDR output device. Administer per AT&T System 75 and System 75 XE—Implementation (555-200-651) and AT&T System 75 and System 75 XE—Administration (555-200-500). For R1V2 or R1V3 systems only, a TN726 data Line circuit pack may be used and PDMs, TDMs, or 212-type modems are not required for the DTE. Connections between the switch and the SMDR output receiving device is the same as a customer-provided data terminal (Figure 5-24). Interface Cabling to SMDR Output Device Figure 5-25 shows the cabling required to connect the TELESEER* unit, printer, or customer-provided DTE.
